10 3ml Syringes Teeth Whitening 44% Carbamide Gel Tooth Whitener Bleach Professional Dental Kit by White Teeth Global (TM)

works great, but I use a one-piece mouthpiece. I don't like the mouthpieces that came with it but the whitener itself is better than anything you find at a local retail store and more economical in comparison to getting professional whitening at the dentist. Would suggest this company switch to a one-piece (top and bottom) mouthpiece instead of two separate. THe separate mouthpieces are annoying.

Not bad

What dentist? Instead of Zoom at $300.00 a pop, I looked at the ingredients...well, the same! Save your cash and buy these! I have a Hollywood Smile for a reasonable price.

Works hella good. I'm trying to quit smoking so I figured having super white teeth, and the possible staining of them would be a deterrent to smoking.

I've been using 15% carbamide peroxide for a while now, and this stuff is weaker. I'm very disappointed that I bought this and that it's falsely advertised.

This stuff does work but the taste is truly horrible!! Using the little light that came with it was a pain. I wear Invisiline braces and used them rather than the bleaching trays that came in the box. You need to dip each tray into hot water and then quickly stick it in your mouth to make a mold. I tried to get the trays shaped etc and basically ended up with a a shrunken mess. I didn't consider that a negative since I had trays already but if you don't, be careful!! You only get the one set and one try to make them work. My most important negative with this product is the taste!!

Didnt work

I'm giving this as 4 so far.......I have only used it 2 treatments....I did get the expensive process already so I had the custom trays. Also the gel is not tasty but at the same time the professional treatments aren't tasty so deal with it......More on the way after I week or two.
